font-family:Arial'>po delsi pauze jsem se dostal k nedavno diskutovanemu
problemu s oddelenim satelitniho prijimace od LNB konvertoru, ktere jsem asi
pred mesicem ci dvema inicioval.<o:p></o:p></span></font></p>

font-family:Arial'>Vyzkousel jsem zde doporucene schema s LM317 a
optoclenem. Funguje to, ovsem narazil jsem na problem s pouzitim 10uF
kondenzatoru, ktere maji propustit 22KHz od prijimace k LNB pro prepinani
pasma. Po jejich zapojeni se rozhodi vystupni stabilizator v satelitnim prijimaci
a misto 14/18V je na vystupu kolem 12-14V, takze pak nespina optoclen, ale
hlavne muze dojit treba k prehrati vystupniho stabilizatoru v satelitu...<o:p></o:p></span></font></p>
